Excellent ProductPerfect as an Anchor. It's compact and once installed would be very difficult to remove without destroying the concrete base it is fixed to.
Plus if you purchase a secure chain, it increases the difficulty of removing the anchor.

Decent apparent strengthThis floor anchor was a bit larger than I had expected. It has 3 anchor bolts and looks and feels very strong. I have bought and installed several different brands and types - and also when relocating had a go at "removing" them with every tool and lots of time available. They are NOT the weak point! Your chain and padlock are far easier to attack. This seems like an excellent choice and a good price point too.When not in use, the shape is designed to be unobtrusive for moving about as it folds down, but I would avoid driving a car directly over it.

Will this fit a large D-lock?

Yes this will fit most locks. The inside measurement of the loop is 50x70mm. The lock is larger then it seems in the picture, the Black base has a 200mm diameter.

Will Kryptonite New York Noose / Extreme Chain fit?

I am interested in combining this product with either the Kryptonite New York Noose chain or the Krytonite Extreme chain. Will the chain links for the two above-mentioned items fit through the securing ring of the anchor?

Yes it fits.

This is advertised as sold secure Gold. However, there are no such markings on the packaging or product.

I need bicycle sold secure gold as a condition of my insurance. Can you confirm this meets the requirement?

it is listed in the sold secure 2015 catalog http://www.soldsecure.com/wp-content/uploads/2015/02/Sold-Secure-2015-Approved-Product-Catalogue.pdf

How are the bolts secured?

I am thinking of using the Ground Anchor in my workshop, but any intruder would find no end of tools with which to attack it. I presume the bolts hidden or in some way tamper proof?

Asked by: DavidShaw

You tap ball bearings into the allen key fitting and then a larger bearing to cover the space over the bolts. This means that it'll still be there when you move house!

Suitable in a wooden shed (with blocks underneath)?

I'm thinking of getting one of these for use in a wooden shed. I'd drill through the wooden floor and continue into standard concrete (solid) blocks underneath the shed. Has anyone tried this approach? Would it be suitable?

Asked by: bbolger

I cannot see any issue with set up.

How thick a concrete slab is required?

Asked by: NickBroon

Bolts go down about 6 cm, so I suppose at this depth or thicker.

Can this be set into a brick wall on the side of a house? Or into large paving stones that are joined by concrete?

Asked by: hubbers

yes it can but security level reduced as brickwork is not as strong as concrete

What size are the supplied drill bits?

I would like to know if my drill will be suitable (a cordless Makita - maximum bit size is 13mm diameter).
Also - could you fit two cable locks through this, to secure two bikes simultaneously?
Thanks in advance.

Asked by: stromule

Your drill might struggle with the supplied bits. I used different fittings which required a smaller drill bit.
And yes its big enough to attach 2 bikes

I have 2 bikes in my shed will this product secure 2 D-locks?

Asked by: St3vieR

The loop itself has internal dimensions of 65x45mm. You could get two d-lock bolts through this space but usable angles might make it very difficult to secure the bikes.

can this be relocated once installed

Hi,
I'm just wondering if once this has been installed it is possible to relocate it? i.e. move to a different position in a shed?
